## Summary

Solaria, founded in 2002 and listed on the Madrid Stock Exchange (BME), is a Spanish solar manufacturer with a reported production capacity of 1.658 GW and a workforce of 235 employees. AKCOME, founded in 2003 and headquartered in China's Zhejiang Province, operates a 6 GW panel factory in Huzhou and is listed on the Shenzhen Stock Exchange. On institutional standing, Solaria carries a meaningful advantage in European markets: its BME listing and EIB-backed financing frameworks give it a visible track record with project lenders. AKCOME, by contrast, is currently not classified as Tier 1 bankable by BloombergNEF, a gap that can slow non-recourse financing for large projects even where the technology itself is sound.

Solaria's 27-panel catalog averages 435.9 Wp and 19.96% efficiency, topping out at 680 Wp and 21.92% - a respectable but mid-range position. Only around 19% of the lineup is bifacial, and its dominant cell technology is not publicly detailed, pointing to a portfolio calibrated for mainstream residential and light-commercial rooftops rather than ground-mount utility work. Warranties average 26.5 years. AKCOME's three tracked products are an entirely different animal: 100% bifacial, 100% HJT, averaging 671.7 Wp and 21.63% efficiency with a top module at 700 Wp and 22.54%. Its temperature coefficient of -0.24%/C per Pmax is markedly better than Solaria's -0.36%/C, meaning meaningfully less power loss in hot-climate installations. A 30-year warranty across the range reinforces AKCOME's pitch to buyers who want longevity-focused, high-yield ground-mount or commercial flat-roof deployments.

For a typical buyer in 2025, Solaria is the safer default for EU residential and commercial rooftop work, where a European-listed manufacturer and broad module variety simplify both procurement and grid-connection paperwork. AKCOME offers genuinely superior specifications - the HJT efficiency edge and thermal stability are real differentiators - but the absent Tier 1 rating is a material constraint for any project requiring institutional debt financing. Self-financed corporate or industrial buyers, and those in markets where Sinosure-backed credit is acceptable, will find AKCOME's numbers hard to match at comparable price points.
